AUTOMATIC GATE.

SPECIFICATION forming part of Letters Patent No. 569,269, dated October 13, 1896.

A pfi ation fil d November 18, 1895. Serial No. 569,387. (No model.)

To all whom, it may concern.-

Be it known that I, DALTON K. IVILSON, residing at Crystal, in the county of Tama and State of Iowa, have invented a new and Improved Automatic Gate, of which the following is a specification.

This invention relates generally to gates, and more particularly to that class known as hand-operated-lever openers, in which the gate is opened by levers disposed at the side of the road.

The invention therefore, primarily, has for its object to provide a gate of this character of a simple and inexpensive construction, which shall be thoroughly braced throughout, conveniently balanced, and easily manipulated.

With other objects in view, which will hereinafter be referred to, the invention consists in the peculiar combination and novel arrangement of parts, such as will be first described in detail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings,in which Figure 1 is a perspective view of my automatic gate in its closed position. Fig. 2 is a sectional view of the same, taken practically on the line 2 2 of Fig. 1. Fig. 3 is a view taken on the line 3 3 of Fig. 2. Fig. 4 is a detail sectional plan view taken on the line 4 4 of Fig. 3. Fig. 5 is a detail view hereinafter referred to.

In the accompanying drawings, A indicates a fence-section running alongside the road, 13 a transverse fence-section, and O the gate disposed across the road, which may be of any suitable construction, but preferably of wooden beams and longitudinal wire rods, such rods in practice being arranged close together to make the gate hog-tight.

0 indicates the hinge-post, and O the latchpost, between which the gate 0 is arranged, as clearly shown in Fig. 1, by reference to which it will be seen the hinged member (3* has its inner face flush with the inner face of the hinge post O, and has upon that face eyebolts 0 c, which engage hook-bolts 0, projected diagonally outward from the corner of the hinge-post G, as clearly shown in Fig. 5, and for a purpose presently explained.

At one side of the fence A, at a suitable distance from the hinge-post, is disposed a and such beam is braced to the post by the braces F F.

On the ends of the beam are clevises D D, to which the hand-levers D D are pivotally connected; These levers D D have eyebolts II II at their lower ends, which are linked by the members I I to a long link K, connected to the lower end of the swinging arm K, which has at one end it a number of chain-links To these are connected the ends Z Z of jointed rod-sections L L, one of which, L, is pivotally connected to a rigid bracket-arm M,projected out from the gate 0 near the hinge -post, while the other, L, is connected to one end of a bell-crank trigger N, fulcrumed on a rod P, secured to the gate beams in the manner clearly shown in the drawings.

The trigger N connects with the latch-rod O, which at the front end connects with the latch-bar N, held normally pressed to its outer position by the spring 0, which abuts against the keeper M as shown.

Q indicates a curved iron bracket secured on top of the post 0 and arranged diagonally, that is, facing the corner of the post from which the hook-bolts 0 project, the upper end being bent inward and secured to the beam E. To this bracket is connected a hook R, joined to one end of a coiled spring S, the opposite end of which is connected to a link-hook R, joined to a clevis T, secured to the top beam of the gate, as clearly illustrated in Fig. 1.

The object of hinging the gate to the corner of the post 0 and placing the bracket diagonally on the top of such post is to pro vide for a stored-up spring-power to complete the movement of the gate after it has been partly swung by the operation of the lever devices, such operation being best explained as follows:

The gate being in the position shown in Fig. 1, by pulling on the pendent hangers G the latch will be first pulled back by rod L, which at this time is straight, after which the gate will be pulled in the direction indi cated by the arrow until it reaches a midway position, at which time both of the link-rods L and L will have been pulled out straight and the draft or pull strain on the rod L, exerted by the lever D, will cease. Now owing to the peculiar manner in which the gate is hinged to post 0 and the arrangement of the springs Q and S it follows that as the gate is swung a tensile pull is exerted on the spring Q, the thus-stored-up power of which as soon which the spring Q, will again serve to movev the gate to its final stroke.

From the foregoing description, taken in connection with the accompanying drawings,

it is thought the advantages of my improved construction and arrangement will readily appear.

It will also be understood that the exact details of construction can be varied without departing from the broad principles of my invention.

It is also obvious that the partsconstituting the gate may be made of difierent sizes. Having thus described my invention, what 'I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the beam and opcrating-levers, ofthe gate pivoted as described, the pivoted arm operatively connected with the levers, the bracket-arm attached to the gate, the link-rods connecting said bracket-arm and pivoted arm, the latch-bar and pivoted trip, and the link-rods connecting said trip and pivoted arm, substantially as shown and described.

2. The combination with the beam and the brace-arms, of the operating-levers pivotally supported from the ends of the beam, the pivoted arm attached to one of the brace-arms,

the flexible connections between the ends of the levers, and the pivoted arm, the bracket- ,arm attached to the gate, the latch-bar and the pivoted trip, and the link-rod connections between the ends of the pivoted arm and the bracket-arm and trip, all arranged substantially as shown and described. 7 3. The combination with the hinged gat having the bracket-arm M, and the latch-bar N, of the pivoted trip for operating said latchbar, the hand-operatedlevcrs D D, the; pivoted arm K, the flexible-connections-joining said arm and the levers, and thelink-rods L.

L, connecting said arm with the bracket-arm and pivotedtrip, all arranged substantially as shown and described.

4. The combination with the gate pivoted as described, of the beam and operating-1evers, the intermediate connections between the operating-levers and gate, the; spring Q, attached to the hinged-post of gate, and connected at its upper end 7 to the beam, the spring S, having the hook ends R and R, and

the clevis T, all arranged substantially as shown and described.
